RAZLIČITE GEOKEMIJSKE ZNAČAJKE RAZVIJENE U BAZIČNIM MAGMATSKIM STIJENAMA KALNIKA (SJEVERNA HRVATSKA)
Description (Dublin Core)
eng
Basic magmatic rocks of Mt. Kalnik experienced hydrothermal alteration and low grade metamorphism. In such circumstances the most useful tracers of their magma sources and tectonic settings are REE patterns and other normalized trace element abundance plots. Gabbro, basalt, diabase and two samples of metabasalts were investigated in this preliminary study. Geochemical signature of gabbro points to the mantle source of magma and those of metabasalts indicates continental crust source. According to its features basalt could have been derived from the same magma as gabbro by process of magmatic differentiation. The magma giving diabase arised most probably from mantle wedge enriched by hydrothermal fluids ascending from the subducting slab.

Bazične magmatske stijene Kalnika su hidrotermalno alterirane i metamorfozirane do niskog stupnja. Za takve stijene najbolji pokazatelji izvora njihove magme i tektonskog položaja jesu obrasci elemenata rijetkih zemalja i drugi dijagrami normaliziranih elemenata u tragovima. U ovoj preliminarnoj studiji istraženi su gabro, bazalt, dijabaz i dva uzorka metabazalta. Geokemijske značajke gabra ukazuju na plaštni izvor magme, a one metabazalta ukazuju na kontinentalnu koru kao izvor. Prema svojim obilježjima bazalt je mogao nastati iz iste magme kao i gabro procesom magmatske diferencijacije. Magma iz koje je nastao dijabaz potječe najvjerojatnije iz omotačkog klina obogaćenoga hidrotermalnim fludima koji se dižu sa subducirajuće ploče.
